Liu, Xinwu b30ba3db15 tools:acrn-crashlog: Detect and classify the crash in ACRN and kernel
Since ACRN has the capability to reboot and reboot reason is available
in SOS, acrnprobe could detect the crash of acrn and SOS kernel.

List of added crash types:

1. ACRNCRASH            - crashed in hypervisor, this detection depends on
                          files in /tmp/acrnlog_last(provided by acrnlog).
2. IPANIC               - crashed in SOS kernel, this detection depends on
                          pstore.
3. SWWDT_IPANIC         - crashed in SOS kernel and reboot reason is wdt.
4. HWWDT_UNHANDLE       - only recognize reboot reason is global, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.
5. SWWDT_UNHANDLE       - only recognize reboot reason is wdt, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.
6. UNKNOWN              - only recognize reboot reason is warm, there is no
                          further clues that it's a SOS kernel crash or a
                          hypervisor crash.

Liu, Xinwu 41b39c5e1f tools: acrn-crashlog: Defer the vm events processing when failed
In the original design, acrnprobe marked all handled VMs'events as "synced"
in file vmrecordid(this patch changes the name to VM_eventsID.log).
Currently, the Android log events are not logged if the first attempt at
reading collecting them from the VM fails. This patch changes the logic
so that the acrn-crashlog tool will retry continuously.

This patch defines different tags for handled VMs'events, and only marks
VMs'events "synced" after it returns successfully.

xiaojin2 3e8e607d5b tools: acrn-crashlog: Fix potential issues under acrnprobe
This patch is to fix potential issues, which are reported by static
analysis tool, for acrnprobe.

Changes:
1. Check the return value of sender_id() and get_sender_by_name(),
   since it could be -1 or NULL.
2. Remove the parameter len from create_event, take parameter path
   as a NULL-terminated string as default.
3. Modify for_each_* functions to avoid overflow.

Liu Xinwu f4b2c24380 tools: acrn-crashlog: android events module for acrnprobe
Sync events detected by android crashlog.
In android system, android crashlog is a log collection mechanism,
it will generate a history_event file to record android system events.
Acrnprobe will detect these events by scanning android history_event file.

This module mainly contains two functions:
1. setup loop device for android.img.
2. detect new event occursing in android.

Liu Xinwu 9caa5d72cf tools: acrn-crashlog: channel module for acrnprobe
The channel represents a way of detecting the system's events.
So far, there are 3 channels:
1. oneshot, detect once while acrnprobe startup.
2. polling, run a detecting job with fixed time interval.
3. inotify, watch the change of file or dir.
